Title
(DE) VERFAHREN ZUR HERSTELLUNG VON ZIRKONIUMDIOXIDFASERN
(EN) METHOD FOR THE PRODUCTION OF ZIRCONIUM DIOXIDE FIBERS
(FR) PROCEDE POUR LA PRODUCTION DE FIBRES DE DIOXYDE DE ZIRCONIUM
Abstract
(DE) Zirkoniumdioxidfasern werden durch Verspinnen einer Lösung einer Zirkoniumverbindung in einer Mischung von Ameisensäure mit Wasser im Molverhältnis 1:1 bis 1:3 und anschliessende Sinterung hergestellt.
(EN) The invention relates to zirconium dioxide fibers which are produced by spinning a zirconium compound solution in a mixture of formic acid and water in a molar ratio of 1:1 to 1:3 and then performing sintering.
(FR) L'invention concerne un procédé pour la production de fibres de dioxyde de zirconium comportant les étapes suivantes: filage d'une solution d'un composé zirconium dans un mélange constitué d'acide formique et d'eau à rapport molaire compris entre 1:1 et 1:3, puis frittage.
